AA10VSO10DFR1/52R-VPA14N00

The AA10VSO10DFR1/52R-VPA14N00 pump belongs to the A10VSO Variable Pumps series produced by Bosch Rexroth for closed-loop hydraulic automation where flow must adapt to load. It uses DFR1 pressure-flow control, which modulates displacement to maintain set pressure while trimming flow to demand. The basic position of Vg Max keeps the swashplate at maximum geometric displacement when the control is de-energized, so the circuit can start with full pump output. A differential pressure setting of 200 psi (14 bar) defines the pressure drop that triggers flow reduction, while a hysteresis of 60 psi (4 bar) prevents rapid oscillations around the setpoint. Direction of rotation is clockwise, allowing direct coupling to right-hand prime movers in mobile or industrial drives.

The pump tolerates a maximum working pressure of 4100 psi (280 bar), enabling operation in high-pressure systems such as press tooling or mobile travel drives. A minimum absolute inlet pressure of 12 psi (0.8 bar) is required at the suction port to avoid cavitation during full-stroke operation. The pilot port labeled X is tapped 7/16-20 UNF-2B, providing a standard connection for external control or monitoring lines. There is no through drive, so the N00 configuration means the shaft cannot pass power to additional pumps; this simplifies mounting when only a single hydraulic source is needed.
